Acousticon? B Carbon Hearing Aid Battery

Whether this in a genuine Acousticon B battery, or is a no-name brand that works with specific Acousticon carbon hearing aids is unknown.

However, this battery was used with Acousticon carbon hearing aids beginning in 1910.

 It measured 3 1/16" by 2⅝" by 1⅜" (7.7 x 6.8 x 3.5 cm) and weighed 7.3 oz. (208 g). It was composed of two carbon-zinc cells and delivered 3 volts.
